Abstract: 278,479. Robinson, J. Aug. 13, 1926. Selective signalling systems.-A plurality of wave frequencies or a plurality of modulations impressed on a. single wave are transmitted, and at the receiving station the effect due to the desired signal is balanced out and the effect due to interference is isolated in a circuit or circuits, while both effects are unbalanced in a circuit or circuits T2, and the total effects in these circuits are combined in such a sense that the undesired effects tend to neutralize each other and the desired effects are registered at F,. An interfering signal acting unequally on receiving circuits E1, E2 can be balanced out by moving tapping X along resistance R, but this annuls the balance in T2 of interference acting equally on E1, E2, for example atmospherics. Hence a position of X is found in which the greatest preponderance of signal effect is obtained in F,.

Title: Improvements in or relating to glass feeding apparatus
IPC: C03B7/084
Filed: 1929-06-29
Abstract: 329,880. United Glass Bottle Manufacturers, Ltd., and Moorshead, T. C. June 29, 1929. Delivering molten metal.-A device for feeding charges of molten glass comprises a hollow reciprocating member which, by its movement, is adapted to isolate completely a charge from a mass of glass, and means whereby the charge is subsequently expelled from the device by compressed air or other fluid. The charge, during its expulsion, is caused to rotate about its vertical axis to assist in retaining it in its desired form. The apparatus comprises a forehearth 1 having an outlet orifice 3 through which the molten glass 4 is expelled by the vertical reciprocation of a hollow cylindrical plunger 5. The outlet 3 is provided with a refractory bushing 24' carried by an element 24 which can be rotated by a gear wheel 27 secured to a shaft 28. The upper part of the plunger is formed with lugs 7 which rest on lugs 9 on a holder 6, and a member 10 pivoted on the holder engages between two of the lugs 7 and locks the plunger in place. By raising the member 10, the plunger can be turned and disengaged from the holder. The space within the plunger is connected by pipes 12, 13 with the main air supply pipe 14. A valve 18 in the air pipe 14 controls the supply of compressed air to the plunger and is actuated periodically by an adjustable cam 19 carried by a rotating plate 20. The pipe 14 is also provided with an air bleed valve 21 which is operated periodically by another cam 22 carried by the plate 20. The shaft of the plate 20 also drives the shaft 28 of the rotatable bushing 24. In operation, the plunger 5 is reciprocated in a vertical direction, and in its lowest position, shown in Fig. 1, its lower edge is in contact with the floor of the forehearth. As the plunger begins to rise, molten glass flows through the outlet 3 and into the space within the plunger, as shown in Fig. 4. When the plunger has again descended to the lowest position, the glass within its interior has been isolated from the mass in the forehearth, and this entrapped charge is expelled by compressed air admitted to the plunger by the actuation of the valve 19. The rotation of the bush 24 rotates the entrapped charge of glass as it is expelled and frees it from the sides of the orifice. In the position shown in Fig. 4, the air within the plunger would normally expand and prevent the glass from entering the plunger. This is prevented by the bleeder valve 21 which permits the air to escape, and the rate of escape can be regulated by a throttle valve 23. This valve can be used to regulate the size of the charges delivered by the apparatus by regulating the extent to which the glass rises within the plunger.

Abstract: 723,700. Valves. COAL INDUSTRY (PATENTS), Ltd., and DAY, C. E. Aug. 12, 1953 [Aug. 12, 1952], No. 20298/52. Class 135. Rotation of the stem 12 of a rotary ball valve 10 to open the latter causes a sleeve 14 on the stem to move longitudinally and compress a spring 15, the spring being held in the compressed state by a diaphragm, &c., 16 responsive to the pressure of the fluid downstream of the valve, and when the downstream pressure fails, the spring forces the sleeve down and the valve will be rotated to the closed position. The connection between the sleeve and the valve stem 12 consists of helical threads 13, and the sleeve is prevented from rotating by lugs 30 which engage in guideways 31 in the valve casing. Downstream pressure is applied to the diaphragm through a passage 20, filter 21, a passage 45 through the stem 12, and a passage 22. Flow is permitted through passage 45 only when the stem is in the position corresponding to the fully open state of the valve, and, at other times, the chamber below the diaphragm is exhausted to atmosphere through a bore 23 in the stem 12 and outlet apertures 24. To actuate the valve by hand by means of a wheel 17, the latter must first be depressed until an eccentric dog-clutch 19 on the end of the wheel shaft 18 engages in the end of the stem 12. Wheel 17 is coned as shown to prevent it being tied down in the engaged position and its rotary movement is limited by a pin 38. Abutments 41 attached to the lower end of stem 12 limit the rotary movement of the valve. Pins 43 ensure the correct positioning of the conduit connectors 34.
